Miniature Bearing
Hebei Naimei Bearing is specialized in making a great variety of bearings,such as window bearings,bearings 608,bearings 625.Especially we are professional in manufacturing miniature bearings. Miniature Bearing are versatile, self-retaining bearings with solid outer rings, inner rings and ball and cage assemblies. These products are of simple design, durable in operation and easy to maintain; they are available in single and double row designs and and in open and sealed variants. Due to their low frictional torque, they are suitable for high speeds. They are widely used in: 1) Sliding windows and doors 2) Skateboard, skate 3) Electric motors 4) Washing machine 5) Textile machine 6) Power Tools 7) Pumps

Dry test transformer output AC and DC high voltage, high voltage for various types of high voltage test. Dry test transformers are used for on-site testing of insulation performance of various electrical equipment.
Dry Test Transformer Dry Test Transformer Dry Test Transformer is the introduction of the latest foreign advanced technology, the use of advanced production equipment, the use of a coil of epoxy vacuum casting, and CD-type core of the new technology, new materials, and its capacity Compared with the oil-immersed test transformer, it has the advantages of light weight, small size, beautiful appearance, stable performance, easy to carry, no leakage oil, etc. And effectively weakening the magnetic flux leakage increases the dielectric strength and moisture resistance. It is especially suitable for testing insulation performance, DC withstand voltage and leakage current test of various electrical equipments in the power system and various power users. It is the first choice to replace the current bulky oil-immersed transformers.
Technical indicators:
1. Impedance voltage: 12%
2, the output voltage waveform: Industrial frequency: sine wave 3, surface temperature rise: <55 °C
4, no-load loss: 0.2% -0.35%
5, allow continuous operation time: 1 hour 6, indirect operation time: continuous high pressure test controller features:
1. Zero return protection device 2, elimination of residual voltage device 3, high-voltage working sound and light alarm device 4, over-current protection device 5, small size, light weight, new security function test transformer structural characteristics 1, insulation structure layout, according to The "distance effect" principle of the positioner oil uses multi-level insulation. The internal insulation of the transformer is divided into multiple oil passages, thereby increasing the degree of insulation and reducing the volume.
2. Solved the oil leakage problem of TDM series transformers. Since the TDM series transformers do not have oil reservoirs, when the temperature is too high, the oil seeps through the expansion nozzles, and this series of products places the oil filling holes at the top of the casing. The oil in the casing communicates with the oil in the body. Therefore, besides functions such as installing silicon stacks, short-circuit rods, and string pipes, the casing is also equivalent to a transformer oil reservoir.
3. The high-voltage output end of the TDM series transformer is sealed with epoxy resin. Due to the large amount of bubbles generated when the epoxy resin is poured under the normal state, discharge occurs in the high-voltage lead part. The RXOSB series uses metal fittings to hold the lead pens evenly to eliminate discharge.
4. The fuel tank of this series is compact in structure and novel in appearance. Its volume and weight are less than 20% of that of the TSB series.
5. The iron core of this series is a single-frame core type, using DQ type, 0.30mm cold-rolled to silicon steel sheet laminated, using a new special material to be tight, replacing the traditional core-screw. The coil is a concentric cylinder multilayer tower structure.
